    摘要: A system and method are provided for determining electrophysiological data. The system comprises an electronic control unit that is configured to receive electrical signals from a set of electrodes, receive position and orientation data for the set of electrodes from a mapping system, compensate for position and orientation artifacts of the set of electrodes, compose cliques of a subset of neighboring electrodes in the set of electrodes, determine catheter orientation independent information of a target tissue, and output the orientation independent information to a display. The method comprising receiving electrogram data for a set of electrodes (80), compensating for artifacts in sensor positions in the mapping system (81), resolving the bipolar signals into a 3D vector electrogram in the mapping system coordinates (82), manipulating observed unipolar voltage signals and the tangent component of the e-field to estimate the conduction velocity vector (83), and outputting the catheter orientation independent information (84).

    摘要: A removable navigation system (10) for a medical device (12) configured for insertion within a lumen in a body is provided. The removable navigation system (10) includes a sheath (40) operatively configured to cover at least a portion of the medical device (12), a positioning sensor (32) affixed to the sheath (40) and a deformable fixation element (20) disposed between the sheath (40) and the medical device (12). The deformable fixation element (20) is operatively deformed to temporarily fix a position of the medical device (12) relative to the sheath (40) and positioning sensor (32).
